3M 7100076933 Cubitron Ii Roloc Disc 2 Inch 120 Grit

Product Description

The 3M 7100076933 is a 2-inch Cubitron II Roloc abrasive disc designed for precision edge grinding and surface finishing in metalworking applications. It combines 3M Precision-Shaped Grain technology with a Roloc quick-change attachment system, allowing fast disc swaps without tools. The poly-cotton X-weight backing delivers high tensile strength, making the disc resistant to fraying or tearing during aggressive edge work. Rated to 25000 RPM, this disc is suited for use with standard right-angle and die grinders equipped with a Roloc-compatible mandrel. It is sold individually and targets professional fabricators, welders, and metal finishing technicians.

This disc is built for edge work on metal substrates where consistent material removal and disc durability are critical. The 120-grit designation places it in the fine finishing range, appropriate for blending welds, smoothing edges, and preparing surfaces before coating or inspection. The evenly spaced grain layout reduces loading by allowing swarf and debris to escape the cutting face, extending disc life in production environments. It is well suited for both production shop use and field repair work where a reliable quick-change abrasive system is required.

Key Features

• 3M Precision-Shaped Grain provides sharp, cool, and consistent cutting action throughout disc life
• Evenly spaced grain with debris-escape gaps resists loading and extends abrasive life
• Heavy X-weight poly-cotton backing withstands edge work without fraying or tearing
• Roloc attachment system enables tool-free disc changes on compatible mandrels
• 120-grit finishing cut suitable for weld blending and pre-coating surface prep
• Rated at 25000 RPM for use with standard pneumatic and electric right-angle grinders

Compatibility

Designed for use with Roloc-compatible mandrels on right-angle grinders and die grinders that accept 2-inch quick-change abrasive discs.

Installation Notes

Installation is performed by pressing the disc onto a Roloc-compatible mandrel until it locks in place — no wrench required. Verify that the grinder RPM rating meets or exceeds the disc maximum of 25000 RPM before use. Always inspect the disc for damage prior to mounting, and never exceed the rated speed. Eye protection and appropriate PPE are required during operation per applicable safety standards.
